We look at the division of 129157 by 60 
We want to figure out the number of times 129157 can be divided by 60.

On to step 1:
60 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 60

Let's proceed to step 2:
The number 60 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 60

Let's proceed to step 3:
60 can be fit into 129 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 9 after subtracting 120 from 129.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 60

On to step 4:
If we divide 91 by 60, we get 1 and a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 31 after subtracting 60 from 91.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 60

Step 5:
The number 60 fits into 315 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 215.0
The remainder is 15 after subtracting 300 from 315.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 60

Going ahead to step 6:
If we divide 157 by 60, we get 2 and a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 2152.0
If we subtract 120 from 157, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
60 can be fit into 370 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 2152.6
If we subtract 360 from 370, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
60 goes into 100 1 times with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 2152.61
Subtract 60 from 100 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
60 can be fit into 400 6 times, resulting in a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 2152.616
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
If we divide 400 by 60, we get 6 and a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 2152.6166
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 2152.6166 with a remainder of 0.0004.
